To @ZZ whom it may concern.-

Be it known that LHARRY BITNER, a cilizen of the UnitedStates of America, residing at Chicago, in the countyof .Cook and State of Illinois, have invented certain new and usefullmprovements in lLlorse-Powers, of which thezfollowing is a specification.

y In the ordinary` horse power, a large, horizonial master-wheel iscoininonly employed,

y meshing with alsmallpiniomconnected either `directly or indirectly to a tumbling rod, by

means of which thepoweristransmitted-to the driven machinery.` To get thel desired speed,

`it-isnec'essary,tense a comparatively small y `t5 the teeth-or cogs, and frequently breaking some of them away. Various devices have pinion,l therebycausingaf great strain upon 4(heen-tried, to overcome this difficulty, and it .1, iste this particular end that the improvements comprising` my invention are directed. lt, is 'my intention to :accomplish this object by means of an arrangementwhich, instead of throwing the `entire strain upon a single tooth `of the driving pinion land also of the masterwheel,`-shall divide the work among twoy orl moreteeth upon each wheel. I do this by conpstructing the master-wheel either U-shaped in cross section, or preferably in two pieces bolted together',l so that itshall have two inner toothed surfaces facing each other, and by arranging two or more pinions between i these toothed surfaces, each meshing with its i. respective gear and also with one of the pinionsin mesh with the lopposite gear. The power is taken from a single pinion, but, as

` such pinion receives it not only from one side of the' master-wheel,but also from one or more pinions meshing with the other side, the strain is divided up between two or Vmore cogs uponthedrivingpinion,arranged at different points about its periphery. n

Referring to the drawings for an illustration ot' my invention, Figure 1 is a central vertical means of bolts, a2. The wheel rides upon rollers, B, journaled in blocks, h,held in recesses in frame, C.

. with the upper and one with the lower face ot' the master-wheel. As the two pinions are `upon oppositesides of the wheel, this man- The rollers are adj usted towardor from each other by means of set screws, c.

ner of gearing causes bot-h pinionsto turn the lshaft in 4the same direction. Between each of the pinions, d', and the face of themasterwheel opposite to the one with which'said pin,- ion is in gear, is placed a loose pinion, cl2, meshingwith the pinion, d', and the masterwheel. This pinion is journaled in the frame, C, so that it transmits the motion of the master-wheel to the driving pinion with which it meshes, while at the same time reversing said motion to correspond with the motion of the side of the pinion with which it isin gear.y

This, it will be seen, divides the strain upon the pinions, d', between the opposite sides thereof. Fig. 3 shows a slight change in the arrangement, which enables a third pinion to be used, and gains still greater strength because of the further division of the strain upon the gear wheel, d.

The principal advantages of the above described construction are its simplicity, compactness and strength. The master wheel furnishesa cover for the pinions meshing with it makinganeat construction, The increased strength is due to the ydivision of the strain between the'two faces of the master wheel and the two sides of the driving pinions. Thus looking at Fig. 2, the driving pinion, d', meshes on one side with one face of the master wheel, and on the other side with the loose pinion, d2, which, in turn, meshes with the other side of the master wheel. The driving pinion, cl', is subject to strain upon its upper side from the master wheel itself and upon its lower side from the loose pinion, d2, which, in turn, is driven bythe lower face of the master wheel. The strain which would otherwise be borne by a single tooth of the driving pinion and a IOO tooth of the master wheel meshing therewith, is therefore divided between two opposite teeth of the driving pinion, and also between the opposite faces of the master wheel. This division is carried still further in Fig. 3, where two loose pinions, d2, cl3, mesh with different portions of the lower face of the master wheel and with different portions of the driving pinion, d', bringing three teeth of the driving pinion and three teeth of the master'wheel always into position to divide `the strain.

I claim as new and desire to secure by Letters Patentf l. The combination with a master-wheel having two toothed surfaces facing eachother, of a pinion fast upon a driving shaft, suitably journaled, and meshing with one of said surfaces, and a second pinion also suitably journaled and meshingwith the first pinion and also with the opposite teeth of `the masterwheel; substantially as described.

substantially as described.
